ATo .all flo/tom t fnmg/ concerti.:

Be it known that I, @nannies Sinnen, a citizenvof tbe United States residing Vat Orient., --n tbe eonnty of Adair and .State of Iowa., have invented a `Certain new and useful Dnanbar for Harrows., of which the tolli-)wing is .a specification. t

The object -oif my .invention is `.to provide a ol-raw bar for narrows or the like yantan-ged .in sections so that when `driving throitgh a gate "orf less width than the width .orf the sections of narrows, '-tben one section may be swung omer andpositioned vupon one of the other :sections tor permitting .the rseetirnis fof narrows to pass :three-gh `the .gate

Still :a fan'ftber object is to provide `a hin-ge Connection between two adjacent members ,of the 1`dmanr bar wherein one ,nielnber ,may be swung' npon vthe `other member when de- -Isiired and when in operative .posi-tion, the abutting ends of the members will'b-ane a :draw rod -or bolt partially received each 1ot .the abi-tttin-g tends of tbe niernlbers.`

Still :a tart-lier object is to provide .a .-sooket 'binge .struetnne throno'fh Whieb :the draw rod `passes `and into wfhic 1 one .of the members is a' ceired for securely l-iolding the membe fpropeawoperatiafe position.

With these and other objects in View., any ilwention consists in :the construction, .an 'ra gement and combination i the various i utero-'tf -niy dern-ie, `whereby `the :objects oon; 'teniplated are :atta-ined, as hereinafter .frnore hilly set forth, pointed .out in any claims, and illustrated in the accompanying Adrawings. in `which:

@figure 6 is .a detail, perspective View foi' the yh-iilne eonnection between the ad-jacent members fof the draw bars.

ln- .the accompanying `drawings I have used the .re-ference nnnieral 10 to indicate genen-ally xa bar .or member which has fixed to it near its ends, a pair of eyebolts 11.

The .eyebo-lts 1l `in turn have ,secu-red tbe-reto, links 12 Whichiextend toward eaoh 4other and ane .connected to a ,chain 13. A `The `cli-ain 1.3 may either be .connected .to a` tractor or to ithe doable tree oi a .team .of horses.

The `ends `of the bar 10 have mounted therein, eyebolts 14, which Ain turn `are oonneeted to draw rods 15 which .draw rods are of considerable length and have their near ends .screw .threadedfas at 1.6` for receiving the nuts 17..

yAoenter .member 1S has mounted in it a ,pair of eyeboilts 19 ato ,Wfhioh may be oonnested the .center section -oi' a `three section barrow.

Braces 20 l.are ,bolted rto .the center member 1S .and have "their `en dsextendedpin opposite directions .for permitting .the draw loa-rs 15 to pass therethrough. The 'ends of the seo tion 18 :are .tonlned with notches 21 which Areocine snbstantially one-.half 4of 'the draw bars 15.

Members 22 yare hingedly secured .to `the ends `l,ofthe member 18 :as `will hereinafter be described. Eaeh of ithe -ineinbers ,22 `ame ,provided with eye .bolts ,23 `Afor permitting the end sec-tions fof a three section harrowto .be seeured tbeleto..

.Braces 24 tare .bolted to the members v22 and lia-re `their `,ends .bent toward Aeaoh 4other .so .thateaohone-of them may rege-ive adraw rod 15, as clearly shown in Figure l Yof .the dra-wings. .lhe .braces ,524i ,are .preferably it'ornied .of .angle irons, .as cleanly 4shown in Figiue loi .tbe'dra illg- Tb@ bi-l-tgge-oolmeiwil between the center inem-bel .2118 and tbe outside members :22 iS dearly shown `in Figure 6 `lof .the drawings and c'onsists'of a solt@ which torins oneibalf the hinge ,connection v "llhesooket ineniber 25 .has .downturned flanges 26 .through which V,are hextended `bolts 2.7. Zllre .downtnrned -flangesZG 4have .open ings fonmed ,therein vtor ,permitting :the bolts 2li' -to extend therethrough and :through Vthe .center member 18. The .downtnrned {ianges of .the socket members `25 `extend beyond .the .end-s foi: .the .center member 18.

The length oit theieenter member 18 is shown the Adotted lines ..29 'in Fagor@ -6 ot the drawings. The downturned flanges 26 are also formed with openings 30 through which are extended the draw rods 15.

The upper side of the socket 25 is formed with a pair of spaced rolled ears 31 which receive therebetween the rolled ear 32 of a plate 33.

The plate 33 is provided with a number of openings 34 and rests upon the upper side of the end members 22. y

lThe plate 33 forms, together with a socket member 25, a completehinge for the end members 22 and the center member 18, after a pintle rod 35 is inserted in the rolled ears 31 and 32.

Bolts 37 are employed for connecting the plates 33 to the members 22.

rIhe ends of the members 22, which abut against the ends of the member 18 are formed with notches Y 36 substantially the same size as the notches 21 andV when the ends abut each other, a complete opening is formed, which is substantially the same size as the rod 15. l

Themembers 22 when received in the socket members 25, will be securely received therein 4so that when the complete draw bar is used, the end members 22 will be sufliciently braced for carrying out their purose.

p In order to retain the braces 2O and 24 against sliding movement on the draw rods 15, I place a sleeve 38 on each of the draw rods 15, which is received between one of the flanges 26 of the sockets 25 and the braces 2O and 24, as clearly shown in Figure 1 of the drawings.

From the construction of the parts just described, it will be seen that either one of the members 22 which has secured to it a section of a. harrow, can be swung upon the hinge structure and brought to position where it will rest substantially upon the center member 18 and for permitting the three row harrow section to be taken through a gate of less width than the three row harrow section.

The bracemembers 24 are pivotally connected to the draw rods 15, which permits the swinging or hinged movement of the members22, as hereinbefore described.

Either of the end members 22 may be swung depending upon the gate desired to take the harrow through. i

It may be mentioned that my structure can be conveniently used with ya four section harrow, by simply lengthening out the center member 18, and inthat connection, both of the end members 22 may be swung to position where they will rest upon the center member 18. As shown in the drawings, however, it is only necessary to swing one of the end members 22 where it will rest upon the member 18. i f

It will be further noted that the line of pull, which is on the draw rods 15, will come right at the connection between the end members 22 and the center member 18, thereby giving me a very eflicient structure.

Some changes may be made in the constructionand arrangement of the various parts of my invention, without departing from the real spirit and purpose of my invention and'it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope. f

I claim as my invention:

t ends of said centerl member, the abutting ends of the center member and end members having notches therein forV receiving the draw rods, as and for the' purposes stated.'

A barrow draw bar consisting of a center member and a pair of end members, plates secured to the ends of said center member, plates secured to one end of each of said end members, openings in said plates for the reception of draw rods, braces from said center member to the ends of said draw rods 'for bracing said draw rods and braces from said end members to the ends of said draw rods for bracing said end members, 10
